Description

Product Description
The 5kW single phase AC combiner box is designed for residential and small commercial solar or backup systems where a single phase inverter needs to be safely connected to the main distribution board. It serves as a central point for AC protection, isolation, and distribution between the inverter and the load.

This unit incorporates essential protection devices such as circuit breakers, surge protection, and earth leakage protection to safeguard the system against overloads, short circuits, and voltage spikes. It ensures compliance with electrical safety standards while simplifying installation by housing all necessary AC components in one enclosure.

Suitable for hybrid and grid tied inverter systems up to 5kW, the combiner box provides reliable operation and easy maintenance. Its robust enclosure allows for indoor or outdoor installation depending on the protection rating, making it ideal for residential solar systems and backup power applications.
